The PIMIENTO is a Transparent Overdrive with an Active EQ for a frequency boost or cut. Keep the GAIN low and VOLUME high for enhanced clarity. Both BASS and TREBLE knobs are “Active” which means you can effectively boost or remove either frequency from your tone. Adjust to taste. Increase the GAIN to boost your signal and drive your tubes into natural Overdrive. The center switch adds transparency and softens the clipping for a smooth vintage Overdrive.
